Implementing two-qubit gates at the quantum speed limit
Joel Howard, Alexander Lidiak, Casey Jameson +8
The speed of elementary quantum gates, particularly two-qubit gates, ultimately sets the limit on the speed at which quantum circuits can operate. In this work, we experimentally d…
A universal quantum gate set for transmon qubits with strong ZZ interactions
Junling Long, Tongyu Zhao, Mustafa Bal +13
High-fidelity single- and two-qubit gates are essential building blocks for a fault-tolerant quantum computer. While there has been much progress in suppressing single-qubit gate e…
Universal Dephasing Noise Injection via Schrodinger Wave Autoregressive Moving Average Models
Andrew Murphy, Jacob Epstein, Gregory Quiroz +10
We present and validate a novel method for noise injection of arbitrary spectra in quantum circuits that can be applied to any system capable of executing arbitrary single qubit ro…
Merged-element transmon
R. Zhao, S. Park, T. Zhao +4
Transmon qubits are ubiquitous in the pursuit of quantum computing using superconducting circuits. However, they have some drawbacks that still need to be addressed. Most important…
Dielectric loss extraction for superconducting microwave resonators
C. R. H. McRae, R. E. Lake, J. L. Long +6
The investigation of two-level-state (TLS) loss in dielectric materials and interfaces remains at the forefront of materials research in superconducting quantum circuits. We demons…
Efficient quantum state tomography with auxiliary Hilbert space
Ruifeng Liu, Junling Long, Pei Zhang +4
Quantum state tomography is an important tool for quantum communication, computation, metrology, and simulation. Efficient quantum state tomography on a high dimensional quantum sy…
